Look, data for individual eruptions:
Year Volcano Mean Sulphurous Output Source Est. Carbon output during year(s) of eruption
1883AD Krakatoa 38 MtSO2pa Shinohara (2008) 26.14 MtCpa
1815AD Tambora 70 MtSO2pa Shinohara (2008) 48.16 MtCpa
1783AD Laki 130 MtSO2pa Shinohara (2008) 89.44 MtCpa
1600AD Huaynaputina 48 MtSO2pa Shinohara (2008) 33.02 MtCpa
1452AD Kuwae 150 MtH2SO4pa Witter & Self (2007) 67.40 MtCpa
934AD Eldja 110 MtSO2 Shinohara (2008) 75.68 MtCpa
1645BC Minoa 125 MtSO2pa Shinohara (2008) 86.00 MtCpa
circa 71,000BP Toba 1100 MtH2SO4pa Zielenski et al. (1996) 494.24 MtCpa
Notice how all but one of the individual annual volcanogenic carbon outputs, estimated above, dwarf the global subaerial volcanogenic carbon outputs estimated by both Gerlach (1991) & Kerrick (2001).
Gerlach is Guesswork ;-)
- XorNot 11y agoYou really need to qualify what those units are. But also, again, if what what you were saying were true, why does it not show up in the atmospheric CO2 record?
- ommunist 11y agoBecause plants and algae consume co2, this is school biology.
- XorNot 11y agoIf CO2 levels are rising overall, and you claim volcanic eruptions utterly dwarf man made emissions, then years with volcanic eruptions should show an increase in atmospheric CO2 outside of the trend, and years without them should be flatter. This is not shown in any of data. But now you claim plants and algae are consuming all the volcanic CO2. So where is the overall increase coming from then? And I'd they are doing this, why, in non-eruption years, does CO2 not fall greatly due to all this biomass?
